The MP5402M integrates a monolithic, step-down, switch-mode converter with two USB current-limit switches and a charging port identification circuit. It achieves 5A of continuous output current over a wide input supply range with excellent load and line regulation. The output of the USB switch is current limited. Both USB ports support DCP schemes for the battery charging specification (BC1.2), the divider mode, and the 1.2V/1.2V mode, eliminating outside user interaction. The output voltage has programmable line drop compensation. Fault condition protection includes hiccup current limiting, output OVP, and thermal shutdown (TSD). The MP5402M requires a minimum number of readily available, standard, external components and is available in a QFN-26 (4mmx4mm) package.
